SPECIFICATION forming part of Letters Patent. No. 393,777, dated December 4, 1888. Application tiled July l2, 1888. Serial No. 279,702. (No model.)

T0 all 1.0710711, it 71mg/ concern.;

3e it known that I, BRaNsoN McDoNALD, a citizen ot' the lfnitod States, residing at Macksville, in the county ot' Pendleton and State of West Virginia, have invented certain new and useful Improvements in Grain-Tallies; and I do declare the following' to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which itl appertains to make and use the same, reference being' had to the accompanying drawings, and to the letters and figures of reference marked thereon, which torni a part ot this specification.

)Iy invention relates to grain-tallies; and its objects are, tirst, to measure the grain automatically by the pressure ot its own gravity; second, to transmit the actuating-pressure directly to a g'raduated plate revolving before a stationary pointer; third, to cause the infallible and simple notation ot' the aggregate quantity measured in a prescribed period, and, fourth, to attain these ends with structural simplicity and econon'iy. I attain these purposes by the mechanism illustrated in the accompanying drawings, in which- Figure l. represents a side elevation of a grain-measure operatively embodying the essential elements of myinvention. Fig. 2 is a similar view thereof partly broken and in section to show its interior construct ion. Fig. 3 is a sectional view ot the counter, taken on the line k1/ y ot' Fig. 2. Fig. I is a transverse section ot' the counter, taken on the line .r .fr of Fig'. 3. Fig. 5 is a rear view ot the revolving graduated plate. Fig. G is a detail view of the stationary indicator in l'ront ot' which the revolving` plate rotates. Fig. 7 is a detail view ofthe slotted guide-plate which serves to directthe oscillatingmovement of the pressure-transmitting lever. Fig. 8 is a detail view of the pressure-transmitting lever; and Fig. 9 represents the front view of the revolving plate shown in Fig. 5, whose graduations, rotating' with said plate, are indicated bythe stationary pointer axially mounted concentrically therewith.

The same designations indicate corresponding parts in the several views.

In the transshipment and retailing ot grain and cereals it is important to till packages of a uniform size with an invariable quantity without. material loss of time and avoiding eircuity of manipulation. The quantity to be measured is uniformly tixed, so that indicatin media for dilt'erent quantities vary from each other in size only, in all other respects being' species ol' the same genus and illustrations of the same principle.

In the drawings, A represents a receptacle whose altitude and diameter vary with the size ot the package to be filled or the quantitv to be weighed. It:` is mounted upon a washer-ring, A,wh ich serves also asa separating-diaphragm secured rigidly to the frame B ot the weighingmechanism, which is provided tor thc purpose ot` accommodating pressureimparting plate (l ot the weighing' and indicating mechanism, with an annular central recess ctmcentric with the axis ot the stationary pointer K. Ilates o serve to join the parts A and B together, preterz'ibl y by screws, so that different-sized measures may successively be superlnised over the same indicating mechanism.

I) represents the frame ol' Vt he weighing meti-hanisni, which consists ot' a base, D,whose upper surt'acc accommodates the springal, the retraetile torce ot' which restores the plate C to its normal position atter each depression due to a weighingI operation. One end of the spring` )l is attaehtfd, by a screw, BI', to the base D', the other end being t'ree under the movable axis F ot the plate t", tending to restore the saine att er depression. An arm, Il?, held b v a pin or screw, has a bent terminus that serves as a bearing tor the bent pressuretransmitting lever Il, to whose lower end is pivotally held the dog Il', that pushes forward the plate .I b v reason ot the serrations J. A suitable detient, L?, attached by pins L to the spring I., secured on the upper face ot the base D', maintains the plate .I in proper po- .sition at'ter each successive are-like movement.

E represents a cover over the face ot' the indicator, which obviates undue wear or at'- mospheric exposure.

F represents the movable reciprocating axis ot the plate C, which responds to the pressure of gravity ot the substance when a predetermined quantity has accumulated in the receptacle A. This axis is slotted to admit a plate, I, held rigidly therein by pin i? and IOO moving,` synehronously therewith, Whose slot li serves to guide the lateral oscillation ot the upper end ot the transmitting-lever H, to whose lower end the dog,l H is pivotally secured by pin h and `guided by spring 7L. The plate I also has a projecting lug, i, by which the vertical reciproeation of the plate is guided by an arm, G, Whose lower bent surface is rigidly secured to the tace D.

The axis I? moves teleseopieally in the bearing,` F', whose lower surface, F2, serves as a point of attachment for the stationary pointer l after the insertion of the rot-ating plate J, which, by reason of an enlarged base, serves to hold both said plate and the pointer by the same screw, 7o. The bearing F is bifurcated at l to permit and guide the reeiprocations of the plate I. A segmental slot, N', cut in the tace D, permits, respectively, the oscillation ol the lever H and its attached dog` H and the passage oi' the spring' 7i', which serves to `@guide pressure, dueto gravity, ill-depress the plate C against the torce ot' the spring M. This pressure is mediately transmitted to the Counter J, and is indicated by pointer K in the manner already set forth.

Havingthus fully described my improve-4 ment, what I claim is- In grain-tallies, the receptacle A, in Combination with the movable base-plate C, the pressure Whereon is transmitted to the oscillating axis F, slotted to admit a plate, I, held therein by pin 1'?, whose slot 'i' serves to guide the lateral oscillation ot the upper end of the transmitting-lever H, to Whose lower end the dog` H is pivotally scoured by pin 71 and guided by spring h', the transmitting-lever H, the actuating-dog H, and the counter consisting` of the stationary pointer K and the movable plate J, dentated peripherally on its upper surface to be engaged by the dogl l-l and l graduated on its lower face to show the numthe movement of said dog and hold it to its I work in the serrations J. The slot is spanned l' b y a li1nitngpi11,N, whose ends are embedded in the 'face D on either side of the slot and serve to prescribe the movement ot' the lever H.

It will be understood that as often as the t predetermined quantity of grain-say a busheli-has accumulated in the receptacle A its BRASON MUDUA'LD.
